SPECIFICATION forming part of Letters Patent No. 697,162, dated April 8, 1902.

Application tiled November 11, 1897. Serial No. 658,167. (No model.)

To a/ZZ whom t n tcty concern:

Beit known that I, ORANGE O. OZIAS, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Weighing-Scales; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this speciiication, and to the letters of reference marked thereon.

This invention relates to improvements in weighing-scales, especially to that class of scales known as counter-scales. In scales of this type as heretofore constructed considerable inconvenience has been occasioned by the fact that it was impracticable to move said scales around into convenient position for the person operating the same or to eX- pose the reading graduations properly to the light, which in most stores enters from one end or the other of the room. For instance, where the scales have been located on the counter it has heretofore been necessary, or at least most convenient, for the storekeeper to always handle the scales at a point behind the counter, and this necessitates in many instances a trip from in front of the counter to the position back of the counter in order to weigh any goods which might be located at the front. So, too, while under ordinary circumstances the light might be sufficient to permit of the graduations on the beam or computing member, where the scale is a computing-scale, to be read when the scale is placed squarely on the counter, yet on dark days it would be almost impossible to read the graduations with the scale in this position. Furthermore, even where the scales are light enough in weight to permit of their being shifted about on the counter the difficulty of preserving them in their proper adjustment when so shifted is always encountered, for, as is well known, the scales to be accurate should always be operated when the base is level or when the parts have been adjusted to accommodate a certain irregularityin the level of the base or support upon which the scales are mounted-the top of the counter, for instance. This difficulty makes it impracticable to shift the scales about; and the present invention has for its object to provide a construction of scale wherein the operative parts of the scale itself may be turned about conveniently, so as to present the front of the scale to either side of the counter or to the light side of the store and without in any wise affecting the adjustment of the scale or in any wise-interfering with the proper manipulations of the scale.

With these objects in view, then, the invention may be said to consist inascale having a subbase, so to speak, which may be leveled upon the counter or other support, and in a corresponding 4scale-base with a circular 65 track, and antifriction-rollers interposed between the base and subbase, upon which the scale may be turned, so as to present its proper side to any point of the compass Without in any wise affecting the adjustment of 7o the parts.

The invention further consists in connecting the base and subbase in such manner that the parts will not become separated when the scale is lifted or transported from place to 7 5 place, and, further, in providing on the base of the scale, so as to be turned with said base,

a suitable support for the supplemental weights, whereby said weights are always located in proper position relative to the front 8o of the scale so as to be conveniently reached regardless of the position of the scale.

Theinvention further consists in providing a check for retarding the movement of the base upon the subbase, whereby its too-free movement is prevented and theparts are held with sufficient rigidity at any position of adjustment to permit of the use of the scale without danger of its being turned in such use. 90

Referring to the accompanying drawings, Figure l is a top plan View of a scale-base embodying my present invention with a portion broken away to illustrate underlying parts, the form of scale to which the base is adapted being fully shown and described in my prior patent, No. 581,17 2, dated April 2O,` 1897, and being of what is known as the even-balance type, although in the application of the present invention it is not my Ico intention to limit the invention to any particular type of scale. Fig. 2 is a section `taken transversely of Fig. l on a central Vervthe pivoted beam or members constituting the main working partsof the scale, the type of scale selected for illustration being, as before stated, similar to that fully shown and described in my said prior patent and will not, therefore, be further referred'to herein. The said scale-base A is further .provided with a substantially flat and preferably circular lateral extension A', constituting, with the part A, what may be termed the scalebase proper.7 This scale-base A A is provided around its edge with a downwardlyextending flange a, and beneath it I locate the subbase D, which subbase D is provided with a circular track or way d, upon which antifriction-rollersE,journaled in the scalebase A, are adapted to travel. The journals for these antifriction-rollers (lettered e) are preferably supported at one end in the flange a and atthe opposite end in lugs a', arranged parallel with the flange a on the inner side of the Abase A. The subbase D maybe in the form of a spider or substantially iiat frame, and at the center D it is provided with apivotal connection with the scale-base A A'. In the preferred form the scale-base is provided at its center of rotation with a spider or frame F,which may be secured in place by screws f and is provided with a downwardly-extending hub or boss E", up into which a screw Gr, pass# ing through the subbase D D', is adapted vto screw, thereby uniting the parts and 'at the same .time permitting the scale-base to rotate freely and independently of the subbase.

To insure a firm union without danger of the screw becoming loosened in use,-the hub F may yextend down through the Aupper portion of the subbase at D and the screw Gr be employed to fasten an enlargement G upon this hub F', which enlargement taking beneath a shoulder g fastens the two parts together securely and holds them against separation or lateral movement.

The subbase D is adapted to be leveled up upon the counter or other support, and when so leveled it is obvious that the rotation of the scale-base thereupon will in no wise throw the scale proper out of its horizontal position, and hence there is no danger of the parts being thrown out of adjustment by such rotation. Any ordinary means may be employed for leveling up the subbase; but I prefer toembody with said subbase a means which will be independent of the counter or support and which will go with and form a part of the' subbase-such, for instance, as the screws or In the form shown the scale-base is provided I at one side with a projection or shoulder K, carrying receptacles k k for the supplemental weights to be used in connection with the scale. This arrangement of mounting the support for the supplemental weights on the scale-base, so as to be movable around the center therewith, it will be observed, maintains the relative positions of the scale and weights, whereby the storekeeper always has said weights where he can at once lay his hand upon them without even looking at the weights to ascertain if they are correct, as storekeepers, as a rule, become so familiar with weightsthat if they are in their proper positions relative to the scale they know at once whether .they have the correct weight in hand.

Inasmuch as there is some little danger of the scale turning when being used if mounted upon a subbase in this manner, I prefer to provide a retainer for holding the scalebase in any position to which it m-ay beadjusted, which retainer, however, will be released when sufcient pressure is applied tending to turn the scale in either direction. In the preferred form this retainer (see Figs. l and 3) consists of a spring-pressed bolt M, having a conical end adapted to enter recesses or apertures Nv in the subbase. The bolt M is mounted in the housing O in the scale-base and is advanced, preferably, by a coiled spring o.

Obviously any preferred form of retainer or lock may be employed, but that shown is i preferred, inasmuch as it is vsimple and not liable to be disarranged or interfered Ywith by meddlesome persons.

It will be observed that so far as the appearance of the scale is concerned the addition of the subbase with the intermediate parts for permitting the scale to-be turned around upon the subbase does not alter the appearance of the scale to an appreciable extent and for all practical purposes would not lead one to suppose that it was other than an ordinary scale. Thus while the advantages of the present invention are secured the structure is practically concealed from view and does not tend to further complicate the appearance of the scale.

The stationary part or subbase is of less dia ameter than the least diameter of the scalebase, or, in other words, the scale-base overhangs the subbase and conceals the same from view.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In an apparatus such as described, the combination with a subbase made in the form of a iiat spider, vertically-adjustable feet arranged around the periphery of said spider IOO IIO

vented, a series of notches on the subbase lo and a movable projection on the scale-base cooperating with said notches to hold said parts against accidental relative displacement. l
